The present invention will be described in more detail now with reference to all accompanying drawings, wherein:
Fig. 1 is a synoptic diagram, and an example of the system of the method according to this invention is implemented in expression,
Fig. 2 represents a step in the method according to this invention, wherein, has generated the password of user's special use,
Fig. 3 is a schematically process flow diagram, and it has embodied an example of the method according to this invention, and this illustrates during a user's of checking first device identity, some important steps that taken place in second device.
Embodiment
Fig. 1 represents to use a computer network of the method according to this invention.One first device 1 is a computing machine in network in this example, directly or indirectly is connected to one second device 2, makes data to be sent to another from one of them.In this certain embodiments, second device is a server.First device is connected to second device 2 by a data link 3.Data link 3 can be a network as the LAN (Local Area Network), a kind of dial-up connection, and perhaps a kind of the Internet connects.
A user of first device 1 wishes login, so that for example from second device or other the device retrieving files that connected from network.Provide available password, comprised a very long Bit String to this user.This password is unique to the user.In addition, the method that can also use certain that user is connected with password.This may be one group of code in the part of very long Bit String, perhaps a user name, perhaps computing machine 1 sign.
In the certain embodiments of Fig. 1, in the data carrier 4 of taking the CD form, provide available password to the user.Also can use the data carrier of any other type.When first device 1 when being a computing machine, data carrier can be, for example, and a flexible plastic disc, DVD disc or a box tape.Be connected to first device 1, perhaps as first device a, part of 1 be certain device 5, in order to read password.In Fig. 1, this is a CD Player, but it also may be a DVD player, perhaps is suitable for certain other devices of the content of sense data carrier 4.
For fear of user's content of copies data carrier 4 directly, it is coupled with Copy Protection.This resist technology possibility for example, comprises some bad sector are arranged at CD 4.Most of CD write devices all can not be handled the data from bad sector.Second device 2 can keep a record of each bad sector.Just exempted thus being included in the request of one section password in the bad sector.
Fig. 2 is shown schematically in the generation of password in a preferred embodiment of the present invention.To the user is that a unique source code 6 is sent to password generator 7.Password generator 7 is a randomizer preferably.But it also is understandable that password generator 7 uses some other algorithm.Password generator 7 generates the password 8 of user's special use, comprises a very long Bit String.In a step of the method according to this invention, the son section 9,10 of the password 8 of user's special use can be selected for from first device 1 and send to second device 2.
The length of password and size of data thereof were just determined by its publisher before this system is set.In order to determine the length of password 8, it is important having two standards at least.
In the system of Fig. 1, first standard is exactly the capacity of data link 3.In other system, lead to capacity good standard normally of the fastest data link of a typical computing machine in network.If this computing machine is connected to the Internet, then the speed of the Internet link will become conclusive standard.Because password has the potential danger that causes havoc in this approach of diffusion on the Internet, so a main aspect of the present invention prevents that exactly password from spreading by the Internet.The password size of data is selected like this, makes it to surpass the interior at certain time intervals data volume that can transmit of data link 3.The selected long enough that gets of this certain time interval is shared password to stop users.In a such self-contained network of image pattern 1, this may be the thing of several hrs.If this computing machine can be connected to the Internet, then can select a longer interval, for example, 10-12 hour.Under any circumstance, this time interval should long enough, makes that downloading whole password 8 is not have attractive force terrifically.
Second standard is exactly the memory capacity that the data carrier 4 of available password 8 is provided to the user thereon.Under the situation of CD-ROM, its maximal value is about 640Mb.Using all told of carrier 4 is favourable so that the highest security level to be provided.This method is not set the upper limit of Bit String length.
Why be like this, by watching Fig. 3, this problem is just clear, in Fig. 3, has described a schematically process flow diagram of an embodiment of method of the present invention.When the figure shows a user's (for example, computing machine 1 user in Fig. 1) who works as checking first device 1 identity, some important step that in second device 2, is taken place.
After data carrier 4 had been inserted into CD Player, device 5 was read password, and first device 1 sends a logging request, and it is received at first step 11 by second device 2.This request or keyed in by the user may be used one section helper, perhaps when CD or data carrier 4 are inserted into reader that is connected with first device 1, is automatically produced by helper.Logging request can provide information about this user or first device, 1 identity to second device 2, makes this user to connect with password 8.
The method that alternatively, may comprise a kind of identifying user from the selected son section 9,10 of first device, 1 password that sends 8.Under latter event, one or more son sections 9,10 of password contain a group id code, in order to identify this user.Second device 2 can take out this group code immediately from relevant section, with it this user is linked to correct reference data.
Because password 8 is so long, to such an extent as to can't in any rational time interval, pass through data link 3 with its transmission, so, will be less by first device 1 in size to the selected sub-section 9,10 of the passwords 8 of second device, 2 transmissions.Can set total size of data of selected son section 9,10 in advance.Preferably, it is selected like this, makes whole verification process short as much as possible, the security that still keeps proper level simultaneously, as above when Fig. 1 is discussed cited.
In a preferred embodiment, when at every turn must identifying user identity, in second step 12, second device 2 be just selected different son sections 9,10.Since meet the different son section 9,10 of all using password 8 each time, thus be captured in the son section 9,10th that is sent in the once meeting, nonsensical.Listener-in 1 ', 1 on data link " still can't in once follow-up meeting, pretend to be this user.In order further to improve level of security, second device 2 can be chosen as son section 9,10 at random and send.
Share among the independent embodiment of spendable the method according to this invention in the unquestioned occasion at password, this respect allows to use short password.Owing to all select different son sections when needing identifying user identity, at every turn so listener-in 1 ', 1 " still need to eavesdrop first device 1 and second a large amount of the communicating by letter of installing between 2, to determine whole password.Therefore, this aspect of the present invention is no matter password how long, all by using a password to carry out any method of authentication, has strengthened security.
The another kind of embodiment of this method also is possible, and wherein, the user of first device 1 just can ask login by only sending the selected part of password 8.This will be for the user provides bigger easy to use, because he only needs device 5 that data carrier 4 is inserted in order to read password, to start authentication process itself.One section helper on first device 1 is handled all the further communications with second device 2.
When the user does not generate logging request on one's own initiative, the request that is received in first step 11 also will contain his identification presentation.In this case, just the step of describing 12 can be omitted, unless need the further exchange of the son section 9,10 of password 8.In such an embodiment of this method, for example, because always identical son section 9,10 are sent out, perhaps since they be according to first the device 1 or it the user can with certain algorithm be selected, so, son section 9,10th to be sent is determined well in advance.
In step 12, selected after the son section 9,10 to be asked, at next procedure 13, to the request of first device, 1 transmission about these specific sub-sections 9,10.First device 1 is searched this a little section 9,10 of password 8 immediately, and they are mail to second device 2.In the above-mentioned another kind of embodiment of this method, wherein comprise each son section of password from the request of first device 1, this step 13 can be omitted.
Follow-up step 14 is features of the common method of all embodiment that can expect.In step 14, second device 2 receives the son section 9,10 of password 8 from first device 1.
Now, each that has received section must compare with each reference field.The step 15 that all contains at all embodiment of the present invention, in 15 ', second device 2 takes out or generates each reference field.In a preferred embodiment of the invention, second device 2 is not preserved a complete copy that is used for the password 8 of comparison to be removed.Would rather in meeting each time, generate password 8 or selected son section 9,10, and subsequently with its deletion, to save storage space.For each son section 9,10 of necessity of generating password 8, use this user's of sign information.This information can, for example, be used to take out a source code 6 of user's special use of storage separately, for the usefulness of password generator 7.Alternatively, this information can comprise the source code 6 of user's special use.
In an alternative embodiment, wherein, user's identity is comprised among each section of the password that receives from first device 1, carries out to take out or each section of generation password is used for the step 15 of comparison ' added a step 16 before.Step 16 comprises the user's who determines first device 1 identity.When each section that will receive compares with each appropriate reference field, will use this identity.
Each follow-up step 17,18,19 couples of all embodiment of the present invention are common, wherein, compare with each reference field from first each section 9,10 that installs 1 password 8 that receives, and in step 18, this user's identity is confirmed as vacation, perhaps passes through authentication in another step 19, and this depends on the result.
If all regenerated each reference field of password 8 when carrying out this method by second device 2 at every turn, then this method comprises an additional step 20 of deleting these reference fields.So just saved the storage space of second device 2.Also make have the people want in second device 2, to search password 8 or its each section become impossible.
The professional person will recognize that the present invention is not limited to each above-mentioned embodiment, in the scope of claims, can change these embodiment in several ways.For example, can provide password to the user by by means of some other mode beyond the data carrier.Equally, can pass through multiple different technologies, the data carrier that contains password is carried out Copy Protection.
